In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The embodiment of the present application provides a drilling vessel, which can be used to implement the following submersible recovery and deployment method. For example, the drilling vessel includes a storage compartment 100, see Figure 1 A cable storage member 210, a traction member 250 and a first lifting member 310 are arranged in the storage compartment 100. A cable 211 is arranged on the cable storage member 210. One end of the cable 211 is wound around the traction member 250 and the first lifting member 310 in sequence. An accommodation space is reserved in the storage compartment 100, and the accommodation space is used to accommodate the submersible 400. Optionally, the submersible 400 is an unmanned remotely operated vehicle (ROV). Optionally, the cable 211 can be an umbilical cable.

[0044] See also Figure 2 The embodiment of the present application further provides a submersible retrieval method, which is used to retrieve and release a submersible 400 on a drilling vessel. The submersible retrieval method comprises the following steps:

[0045] Step S110: taking the submersible 400 out of the accommodation space, connecting the cable 211 to the submersible 400, and using the first lifting member 310 to lift and deploy the submersible 400;

[0046] Step S120: Recover the submersible 400, separate the cable 211 from the submersible 400, and move the submersible 400 into the accommodation space.

[0047] The cable storage member 210, the traction member 250, the first lifting member 310 and the submersible 400 and other multiple devices can be placed in the same storage compartment 100, and the structure is compact; the preset space in the storage compartment 100 can be used to place and store the submersible 400, and provide an operating space for the cable connection or cable release operation of the submersible 400. When launching or recovering the storage submersible 400, there is no need to take out or place the submersible 400 from other compartments; this can not only save the space of the drilling ship, but also shorten the distance between the various devices, which is convenient for simultaneous management and control, thereby shortening the time required for deploying the submersible 400, that is, shortening the operation preparation cycle for deploying the submersible 400, and improving the deployment efficiency; at the same time, since there is no need for cross-compartment connection between the various devices, it is conducive to the maintenance of the various devices, that is, the service life of the various devices can be extended, so that the various devices can be suitable for operations with high operation frequency and long operation task cycle. Therefore, the submersible collection and release method provided in the present application can meet the needs of the submersible 400 to perform deep operation tasks.

[0048] Optionally, in some embodiments, a first moving device is disposed in the accommodating space, and a first preset position is further disposed in the storage compartment 100 , and the first preset position is communicated with the accommodating space.

[0049] Optionally, the storage compartment 100 is provided with an opening to deploy and recover the submersible 400. Exemplarily, an opening is provided at the front side of the storage compartment 100. The first preset position is disposed near the opening, the first lifting member 310 is also disposed near the opening, and the accommodating space is disposed at a side of the first preset position away from the opening, that is, the accommodating space is disposed behind the first preset position and the first lifting member 310.

[0050] Optionally, in some embodiments, the step of “taking the submersible 400 out of the accommodation space” in step S110 includes the following steps:

[0051] Step S111 : The submersible 400 is moved from the accommodation space to a first preset position by a first moving device, and the cable 211 wound around the first lifting member 310 is connected to the submersible 400 .

[0052] Optionally, in some embodiments, the above step S120 includes the following steps:

[0053] Step S121: Recover the submersible 400 to the first preset position, separate the cable 211 from the submersible 400, and move the submersible 400 from the first preset position to the accommodation space by a first moving device.

[0054] Optionally, in some embodiments, a second moving device is also arranged in the storage compartment 100, see Figure 3 The submersible 400 includes a main body 410 and a repeater 420 connected to each other. The repeater 420 is disposed above the main body 410. A support frame 521 is disposed on the first mobile device. Optionally, the repeater 420 may be a TMS repeater 420.

[0055] It should be noted that the height of the submersible 400 formed by the connection between the main body 410 of the submersible 400 and the repeater 420 can be as high as 4.5m, which causes the center of gravity of the repeater 420 installed above to be too high. The drilling ship will inevitably shake during its voyage at sea, which will make the repeater 420 with a too high center of gravity easy to shake. The repeater 420 is connected to the main body 410 of the submersible 400 by the cable 211. Therefore, when the repeater 420 shakes, it will drag the cable 211 to continuously apply a reciprocating load to the main body 410 of the submersible 400, which will cause damage to the main body 410 of the submersible 400.

[0056] Therefore, when the submersible 400 is stored, the body 410 of the submersible 400 needs to be separated from the repeater 420. The repeater 420 itself has a relatively high center of gravity and is prone to shaking or tipping over. Therefore, a support frame 521 can be provided on the first mobile device to support the repeater 420 to prevent it from tipping over.

[0057] Optionally, in some embodiments, after “separating the cable 211 from the submersible 400” in step S121, step S121 in the submersible deployment method further includes the following steps:

[0058] Step S1212 : Separate the main body 410 from the repeater 420 , and move the repeater 420 onto the support frame 521 by using a second moving device.

[0059] It is understandable that the above step S1212 can be performed after "moving the submersible 400 from the first preset position to the accommodating space by the first moving device". This arrangement can prevent the first lifting member 310 and other devices from affecting the operation of the second moving device.

[0060] Optionally, in some embodiments, before the step of “connecting the cable 211 wound around the first lifting member 310 to the submersible 400” in step S111, step S111 in the submersible launching and retracting method further includes the following steps:

[0061] Step S1111 : Move the repeater 420 to above the main body 410 by using a second moving device, and connect the repeater 420 to the main body 410 .

[0062] It is understandable that after performing the above step S1111, the step S111 of "moving the submersible 400 from the accommodation space to the first preset position by the first moving device" can be performed. This can also prevent the first lifting member 310 and other devices from affecting the operation of the second moving device.

[0063] Optionally, in some embodiments, see Figure 4 The first moving device includes a telescopic member 510 and a translation member 520 , the telescopic member 510 is connected to the translation member 520 , and the telescopic member 510 is used to drive the translation member 520 to move through its own telescopic movement, the translation member 520 is used to place the submersible 400 , and the support frame 521 is set on the translation member 520 .

[0064] Optionally, a first placement position is provided on the translation member 520, and the first placement position is used to place at least part of the submersible 400, and the support frame 521 is provided behind the first placement position. When the submersible 400 is not in use and stored in the accommodating space, the body 410 of the submersible 400 can be placed on the first placement position, and the repeater 420 can be placed on the support frame 521; when the submersible 400 needs to be used, the repeater 420 can be installed on the body 410 of the submersible 400, that is, the entire submersible 400 is placed on the first placement position.

[0065] Optionally, the telescopic member 510 is a telescopic hydraulic cylinder, and the translation member 520 is a translation plate. Optionally, the telescopic hydraulic cylinder has a minimum stroke and a maximum stroke, and when the telescopic hydraulic cylinder is at the minimum stroke, the translation plate is placed in the accommodation space; when the telescopic hydraulic cylinder is at the maximum stroke, the translation plate can be extended to the first preset position, so that the submersible 400 can be moved to the first preset position.

[0066] See also Figure 3 The second moving device includes a guide rail 610 and a second lifting member 620 . The guide rail 610 is installed above the accommodating space, and the second lifting member 620 is movably installed on the guide rail 610 .

[0067] Optionally, the guide rail 610 may be arranged in the front-to-rear direction so that the second lifting member 620 on the guide rail 610 lifts the repeater 420 and places the repeater 420 on the support frame 521 .

[0068] Optionally, the second lifting member 620 is an electric hoist. Of course, the second lifting member 620 can also be a winch or other lifting members, which is not specifically limited here.

[0069] Optionally, in some embodiments, the cable storage member 210 and the traction member 250 are both electric winches, the first lifting member 310 is an A-type hanger, and the A-type hanger is provided with a stabilizer 311. The first lifting member 310 can lift the submersible 400 and move between a second preset position and a third preset position, the second preset position is set in the storage compartment 100, and the third preset position is set outside the storage compartment 100, and the second preset position and the third preset position are both connected to the first preset position.

[0070] Optionally, the second preset position is also set near the opening, and when the first lifting member 310 is located at the second preset position, the distance between the bottom surface of the stopper 311 and the deck surface of the storage compartment 100 is greater than the height of the submersible 400, so as to prevent the submersible 400 from colliding with the stopper 311 during movement. Optionally, when the first lifting member 310 is located at the second preset position, the first preset position may be located directly below the stopper 311.

[0071] It should be noted that, on the one hand, when working underwater, it is inevitable to involve some frequent acceleration and deceleration processes. Electric winches can directly adjust the speed through the frequency converter, and the speed change process is both agile and rapid; while hydraulic winches need to change speed through throttle valves or switch motors, which is bulky and inefficient. On the other hand, when maintaining electric winches, only the motor and electrical control cabinet need to be maintained; while the maintenance of hydraulic winches requires maintenance of both pipelines and hydraulic pumps, which is time-consuming, labor-intensive, and difficult to maintain.

[0072] Therefore, the use of electric winches for both the cable storage member 210 and the traction member 250 is not only conducive to shortening the operation cycle and increasing the operation frequency, but also convenient for maintenance and can extend the service life, which is conducive to the submersible 400 performing deep-depth operations.

[0073] Optionally, a driving mechanism 320 connected to the first lifting member 310 is further arranged in the storage compartment 100, and the driving mechanism 320 can be used to drive the first lifting member 310 to swing between the second preset position and the third preset position. Figure 5 A schematic diagram showing the swinging process of the first lifting member 310 is shown. Optionally, the driving mechanism 320 may be a high-power pump station.

[0074] The anti-sway device 311 can prevent the submersible 400 from swaying and causing damage when the first lifting member 310 lifts the submersible 400 and moves between the second preset position and the third preset position.

[0075] Optionally, in some embodiments, after “moving the submersible 400 from the accommodation space to the first preset position by the first moving device” in step S111, step S111 in the submersible folding and unfolding method further includes the following steps:

[0076] Step S1112: The cable 211 wound around the first lifting member 310 passes through the stopper 311 to connect with the submersible 400, and the top of the submersible 400 is close to the stopper 311, and the first lifting member 310 swings outboard from the second preset position to the third preset position; lower the cable 211.

[0077] For example, when deploying the submersible 400, the second lifting member 620 can be moved along the guide rail 610 to the top of the repeater 420, and the second lifting member 620 is connected to the repeater 420. Then, the repeater 420 is lifted to the top of the body 410 by the second lifting member 620, and the repeater 420 is fixedly connected to the body 410, and then the connection between the second lifting member 620 and the repeater 420 is released. Then, the cable 211 turned by the stopper 311 is fixedly connected to the repeater 420, and the preparation work before the deployment of the submersible 400 is completed.

[0078] Subsequently, the cable storage member 210 releases the cable, and the traction member 250 drags the cable 211 outboard until the first lifting member 310 is driven by the driving mechanism 320 to swing outboard from the initial position to the second preset position (still inboard) to increase the height of the stopper 311. It should be noted that the first lifting member 310 at the initial position is inclined toward the side close to the storage compartment 100, so when the first lifting member 310 swings outboard at a certain angle, the height of the stopper 311 can be increased (i.e., the distance between the bottom surface of the stopper 311 and the deck surface of the storage compartment 100 increases). In this way, sufficient space can be reserved for the lifting of the submersible 400, so that the first lifting member 310 can lift the submersible 400 and leave enough cable 211 margin, and it can also prevent the stopper 311 from being too low and colliding with the submersible 400.

[0079] Then, the submersible 400 is moved to the first preset position (i.e., directly below the stopper 311 of the first lifting member 310 at the second preset position) by the first moving device. Then, the cable 211 is lifted upward by the traction of the traction member 250 until the top of the submersible 400 is fixed against the stopper 311, at which time, the cable storage member 210 is in the cable-collecting state. Then, the first lifting member 310 is driven by the driving mechanism 320 to swing outboard from the second preset position to the third preset position, and the cable storage member 210 continues to release the cable until the submersible 400 reaches the preset operating depth.

[0080] Optionally, in some embodiments, the step of “recovering the submersible 400 to the first preset position” in step S121 further includes the following steps:

[0081] Step S1211: Recover the cable 211 and make the top of the submersible 400 close to the anti-sway device 311, and the first lifting member 310 swings inward from the third preset position to the second preset position; place the submersible 400 at the first preset position.

[0082] It is understandable that the submersible recovery operation process is the opposite of the deployment operation process, so I will not elaborate on it here.

[0083] Optionally, in some embodiments, a first steering mechanism and a second steering mechanism are further arranged in the storage compartment 100, and the traction member 250 and the cable storage member 210 are arranged at intervals in the vertical direction. The cable 211 is connected to the traction member 250 from the cable storage member 210 through the first steering mechanism, and the cable 211 is connected to the first lifting member 310 from the traction member 250 through the second steering mechanism.

[0084] Optionally, in some embodiments, see Figure 6The first steering mechanism includes a first guide pulley 241 and a second guide pulley 242. The traction member 250 and the second guide pulley 242 are arranged above the cable storage member 210 and the first guide pulley 241. The cable 211 is connected to the second guide pulley 242 after being diverted from the cable storage member 210 through the first guide pulley 241. The cable 211 is connected to the traction member 250 after being diverted through the second guide pulley 242. The second steering mechanism includes a third guide pulley 260. The third guide pulley 260 is arranged above the traction member 250.

[0085] Optionally, in some embodiments, see Figure 1 or Figure 3 A cable tension compensation device 270 is also arranged in the storage compartment 100, and the cable 211 is connected to the traction member 250 from the second guide pulley 242 through the cable tension compensation device 270. The cable tension compensation device 270 can apply a certain pre-tension to the cable 211 during the process of retracting and releasing the cable 211.

[0086] Exemplarily, a bracket 700 is arranged at the rear of the storage space in the storage compartment 100 to arrange the equipment vertically and improve space utilization. A second placement position is arranged at the bottom of the bracket 700, and the cable storage member 210 and the first guide pulley 241 are arranged at the second placement position, and the first guide pulley 241 is located on the right side of the cable storage member 210. The traction member 250 and the second guide pulley 242 are arranged on the bracket 700, and the second guide pulley 242 is located on the right side of the traction member 250, and the second guide pulley 242 is aligned with the first guide pulley 241 up and down, and the cable tension compensation device 270 is arranged at the upper rear of the traction member 250. The third guide pulley 260 is arranged at the upper front of the traction member 250, so that the third guide pulley 260 can lead the cable 211 from a high place, which can prevent the cable 211 from being too low and interfering with the operation of other equipment. Optionally, the driving mechanism 320 is also disposed on the bracket 700 , and the driving mechanism 320 is located on the left side of the traction member 250 .

Optionally, the cable arranger 220 is also arranged in the second placement position.

[0094] On the one hand, by providing the cable reel 220, the cable 211 can be neatly and orderly retracted and released. In other words, by providing the cable reel 220, when the cable 211 is retracted, the cable 211 can be neatly wound around the cable storage member 210 to avoid problems such as tangling of the cable 211; when the cable 211 is released, the cable 211 can be released in an orderly manner. On the other hand, by providing the cable reel 220, the inclination angle of the cable 211 can be controlled when the cable 211 is retracted and released. Optionally, the inclination angle can be 90°.
